We are all familiar with (or should be) the SRND guides from Cisco.
Located here: SRND
I’d like to highlight one that I found particularly useful. It goes in to the concept of a routed access layer. Find it here.
I’m beginning to learn a bit about MPLS and have just completed some MPLS OSPF setup. I must say, it seems a bit more complicated than it’s worth. Ok, so by default, even links in the same area are advertised as type 3 summary LSAs. I’m going to work on the sham-link which is supposed to alleviate this particular issue.
regardless, here’s a few tidbits for studying: make sure you can originate a default route from one CE router and have it picked up as a type 5 LSA in other areas. There are a few tricks to get this working.
(correction: they’re type 3 summary LSAs. I originally said they were type 2)
The CCDE written, as published by Cisco, contains 5 major headings for study.
1. IP Routing.
Note: no IPX or Appletalk or anything else. IPv6 basics is a subtopic under ‘generic routing and addressing concepts’ Other than that, no big surprises. I suppose we’ll be concentrating on best practices rather than odd, non-obvious configurations.
There is mention of tunneling non-IP protocols, specifically NetWare IPX.
Nothing specifically relating to Voice/VoIP, just generic requirements for VoIP.
This section is much lighter than the others.
This section is lightest of all (only 5 subheadings)
Ok, so Cisco recently announced the CCDE certification.
Those old timers out there will remember the ill-fated CCIE+Design certification that apparently NOBODY passed. I wonder if this will suffer the same fate. The problem is how does one test against something that is considered a dark art? Networking is not something that falls easily under an Engineering discipline. Networking is not something that can be quantified or easily measured. People talk of 5+nines availability but even this cannot be easily defined or quantified – 5 nines for what? Applications? Ping? What do you measure? The whole network or just critical pieces of it? Availability is one thing, but reliability is another.
